I got around the issue with using an older boot.img and bootloader. One (or both) are causing issues with my system.

They added a lockscreen - that will make some people very happy.
[G Tablet General] xdadev69:
How did you get around this. I tried this update and it borked my device as well and I can't get past the viewsonic boot screen or load clockworkmod to boot the recovery kernel
[G Tablet General] roebeet:
I used nvflash - I dropped the old bootloader and boot.img in there and ran it with that, and it booted up.

EDIT: I couldn't get wifi working for Quadrant, but Nenamark is ~40fps. My guess is that they updated a lot of the libs so that they in up-to-date with recent Nividia changes.

EDIT2: Camera is working, including rotation. Gsensor is still off for games, but that's not a surprise.
[G Tablet General] xdadev69:
Thank god for nvflash. I thought I seriously boned myself today installing this new UAT version. I flashed back to stock, reinstalled clockworkmod, and then was able to get back up to TNT lite 4.2.4.

While I am posting, I would like to thank all the Devs for their time and efforts making these ROMS and instructional posts. Without your efforts this tablet would seriously blow donkey balls. I actually bought the G tablet with the full intention of getting rid of the stock ROM and unleashing the full potential of the underlying hardware with the ROMS here.

Thanks again

:)

This is not bad at all, I forgot how nice the weather dashboard looked because I was too busy cursing this thing for being sooo slow. I remember the first day I got this thing, I couldn't even stand to use it. It was so frustrating. You,gojimi and rothnic did an amazing job to get this tab where it is today. I think viewsonic even "borrowed" some of you guys work, lol.. Thanks Again for you guys work!

UPDATE: I went completely stock before this update, (no clockwork mod) this new update 3991 looks like it has a built in recovery menu. I don't remember that on older versions
[G Tablet General] lsu205:
what were you running prior to returning to stock?
[G Tablet General] aver2one:
vegaN 5.1.1
[G Tablet General] roebeet:
I hadn't looked at their recovery - very nice. They are emulating what Notion Ink had done on their recovery.

This is going to be a nice update, once they shake out the bugs.

Here's a screenshot of the lockscreen, using the "classic" launcher:
[G Tablet General] slysecretspy:
Looks good, I like the changes.
[G Tablet General] roebeet:
2400 in Quadrant - and that's 3991 "stock", no changes. Normally stock is ~1900, I think.

I managed to get Wifi working by downleveling the Wifi drivers - that was needed to use the older kernel. I just don't understand why their new kernel doesn't work for me.
[G Tablet General] aver2one:
Wow looks like that next update is going to be great!

Btw I was averaging @1700 quadrant score earlier today stock before I went up to 3991
[G Tablet General] flipovich:
Looks/sounds very nice roebeet...can't wait for the push over OTA...I actually just went back to stock a few hours ago to mess with the enhancement pack with the January OTA update...it's actually fairly quick compared to the original stock...think I'll stick with it for a bit :-)

I'm guessing that since it's a non-published update, then they may have an incomplete boot.img or possible they had to update the bootloader, who knows...could also be a "built-from-scratch" update that they are still working on, lol...doubtful but you never know :-)

Good luck and here's hoping for an official push from Viewsonic here soon. The sooner they get this out, the sooner they can get to working on an official Viewsonic release of HC ;-) lol
[G Tablet General] pmcnano:
Wow, that update is great! Though, sorry to hijack the thread, but I got no replies elsewhere, anyone had the "blank screen of dead" issue? I stop using my gtablet for a couple of weeks, and now that I boot it up again, the screen is white! (not even the VS birds..).

Keep pushing updates for us =)!

Thanks
[G Tablet General] aver2one:
Do you have a Backup in clockwork mod? Do you have clockwork mod?
[G Tablet General] pmcnano:
Yea, but again, thats not the issue. Theres nothing in the screen, not even booting to recovery, the screen is white, theres a thread about it, someone reported the same problem, I asked what happened to it, but got no reply! D:

Thanks
[G Tablet General] aver2one:
If you can't boot into recovery have you tried nvflash?
[G Tablet General] flipovich:
You may want to head over to the development forums and check out the nvflash thread by roebeet...sounds to me like you'll need it. Good luck.

Question for you roebeet...how stable is this? Just wondering if I should even attempt to install it. Let me know what you think and thanks for all the hard work.
[G Tablet General] bobolinko:
Found this in my TnT site scan:

http://tapntap.http.internapcdn.net/...-3991-user.zip

Build date is 2/12, and it's still Froyo. It looks like a lot of stuff was touched, perhaps they incorporated some recent Nvidia libs.

EDIT: They have a Flash player script in here - that's new.

Is there an enhancement pack with this, or is it available, even ?

Great men do great things.... like our developers! Thanks guys ALL OF YUU!!!
[G Tablet General] roebeet:
It looks like 3991 incorporates the enhancement pack, already. I think they've finally gotten all the nvidia updates that we incorporated over the last two months.

I'm not sure what to do with this thing yet, given that it is a UAT and the boot.img doesn't seem to work. I might incorporate the system.img next week into a 4.3.0, if they don't release anything by then.
[G Tablet General] pmcnano:
@aver2one @flipovich

I think I didnt explain myself, the device "works", the rom is fine, the problem is that screen is white, even the splash screen (birds) its white, I cant see anything, it boots fine, I can hear the clicks when pressing the capacitive buttons. Meh, thanks for the help anyway, I think it will have to RMA, the problem is that im in Mexico :(!
[G Tablet General] xmr405o:
Well this is encouraging to see. Stock ROM hitting 2400+ quads.

Thanks for the info, Roebeet.
[G Tablet General] xmr405o:
This recovery reminds me of the old SPrecovery.
[G Tablet General] aver2one:
Yeah it does very similar
[G Tablet General] jimcpl:
At first, I was thinking that it was nice that VS was still working on updates for the Gtab, but given that the update borks the Gtab (for roebeet, etc.), I'm wondering if this update was meant for a different machine?

Jim
[G Tablet General] Skempo:
Has anyone else tried installing this update?

And what were your results?

I have been thinking of installing this version, but after reading some of the posts I am a little leary. I have been having very good performance with 3588 and the enhancement pack.
[G Tablet General] brainyjd:
Could you explain a little more about how you corrected the wifi issue. I ripped the boo.img and bootloader out of the update and ran it but still can not get the wifi to work.
[G Tablet General] brainyjd:
nevermind I used one of the boot images from the dev section and it worked fine.
[G Tablet General] muqali:
I live on the Mexican side of the US border and have an American phone/address if you need to give them phone or address information let me know, you can use mine.
[G Tablet General] Butch1326:
Robeet,

I used your TnT Lite 4.2.0 Boot.img file. The 3991 update installed fine.

Now working through the WIFI issue. More to come...
[G Tablet General] Butch1326:
Which one did you use? I used the boot image from TnT 4.2.0, and I'm not getting WIFI to work.

Thanks!!!

UPDATE #1: Attempting to use the 3588 boot.img. More to come....

UPDATE #2: Crashed and burned. I can't even get into Recovery anymore. Trying to work on nvflash, but Nvidia changed their website, and I can't find the Tegra 250 SDK to get the APX driver (using Windows).
[G Tablet General] roebeet:
For the Wifi issue, you just need to adb push everything under /system/lib/hw/wlan from the old TnT ROM to the new one, and Wifi will work (I tested that yesterday).

Technically, we have the foundation for a 4.3.0 with what's there in this UAT. I'm still mulling this over but I might throw out a build, soon. Especially since I need a break from Honeycreamed. I like that the vast majority of our fixes seem to be added to this new build of theirs.
[G Tablet General] b3ltazar:
Stock apps

is there any way I CAN INSTALL THE STOCK TNT APPS WITH YOUR TNT LITE ROMS I ALWAYS GET FORCE CLOSE WHEN I TRY LIKE DASHBOARD HOME NEW EMAIL ECT.. I REALLY LIKE THE FEEL OF THE STOCK APPS! THANKS!! COULD YOU TELL ME HOW TO INCORPORATE THE GSENSOR FIX FOR THIS ROM !! I LOVE YOUR WORKK!!! I USED PERSHOOTS KERNEL TO FIX THE WIFI!!
[G Tablet General] aver2one:
Sounds good!
[G Tablet General] Butch1326:
Thanks!!! I'll give it a try when I get recovery back.

For now, take a break and go get yourself some Ice Combs. Uh-oh, here we go again....
[G Tablet General] roebeet:
Ahhh stop yelling!! :)

For the stock apps, just alter the mod to your liking -- in the /system/app folder of the ZIP, there are replacement apks and if you just remove them the stock apps will show up after a re-flash.
[G Tablet General] b3ltazar:
Sorry about the caps accident! Is there a way to get the gsensor fix into this update? That is the only problem I am seeing so far! Thanks for all ur help!
[G Tablet General] life02:
Does anyone have the Nvidia SDK with the APX drivers handy?... I'm getting an access denied on the http://tegradeveloper.nvidia.com/tegra/tegra-250-developer-sdk page.

[G Tablet General] barakisbrown:
roebeet,

are you leaving us for the xoom?? Are you getting the xoom so you can bring us some honeycomb love??? Do not want to lose a good mod for the tablet we all enjoy.
[G Tablet General] roebeet:
Don't worry - my GTAB isn't going anywhere. But I am getting a Xoom.

I wish I could say that one will help the other, but this HC exercise has been a lot more difficult than expected. :mad:

I was working on a proto-type TNTL 4.3.0 that steals their system.img - I ported most of what was needed, including the rotation fix, but I still have to add nvrm_daemon screen refesh (the old one doesn't work) and the rothnic animation effects. I have to travel this weekend but I'll work on it early next week and release an update.
[G Tablet General] b3ltazar:
sounds good to me anyway i can help or test im here!
[G Tablet General] notsob2002:
Sure would be nice if this was released as a official update from viewsonic to hold customers over until a better update comes out.
[G Tablet General] chili_red:
I was speaking with VS tech support last Thursday asking them about available accessories and during the conversation the tech did state that this 1.2 update had been released on 2/28 and it will take up to two weeks for it to be seen on the OTA for all users.

He also went on to say that they are trying to stick to a end of month release for all updates and there should be another one at the end of March.

Hope they stick to this schedule.
[G Tablet General] notsob2002:
I found that after it is copied and renamed in the root you need to rename it again as it shows as "update.zip.zip" I had to remove the second .zip.

Also... is there another way to copy a recovery folder? I mean do you need one from another rom or can you create one?

Thanks

Dale
[G Tablet General] notsob2002:
I wonder why it would take up to 2 weeks to show when 3588 will show up so soon after you first start the gtab? maybe he ment the next update will be at the end of march in about 2 weeks?
[G Tablet General] JasonSCarter:
I wonder if you are on stock with the enhancement pack if you will be required to be back on stock before getting this new update once it is pushed out? I have only had my G Tablet for a few weeks, so I haven't been around to know if Viewsonic updates work correctly when you have the enhancement pack installed.
[G Tablet General] lsu205:
Roebeet is best to answer that one. For me, running the enhancement pack I never got the OTA (even if clicking updates) when 3588 came out late in January. Got tired of ating and went to site in the 1st post and downloaded it (3588). I don't see where this ones been pushed OTA yet tho.
[G Tablet General] JasonSCarter:
Well hopefully he will see my message. He may have tested this already. If not I guess I am going to have to go back to stock.

Will I have to use NVFlash to go back to stock if I only have the enhancement pack installed? Or can I just grab the download from Tap n Tap and do the regular update.zip with the command file on the SD Card?
[G Tablet General] lsu205:
When I went to 3588 from prior version (with enhancement pack) I did it the normal way (zip file and recovery file). I don't have clockwork installed nor haveIi ever used nvflash. If you update to 3991 you would have to reinstall the enhancement pack (same process).
[G Tablet General] JasonSCarter:
Thanks make sense.

With all the updates Viewsonic is doing, I am wondering if it's worth to install the enhancement pack again? To get the market I guess it would be, but if Viewsonic is making this better and better, then I may just side load apps off of my phone.
[G Tablet General] joejaru:
Enhancement Pack and OTA

You should still get the update over the air if you have the enhancement pack. As the above poster said, it will wipe out the enhancement pack. From what I've read, this update seems to incorporate the nvidia drivers that were part of the enhancement pack. The market and, I imagine, a couple of other fixes/improvements will still be required from the enhancement pack.
[G Tablet General] scrinch:
In the case of a 3991 OTA update, will we be able to restore apps (including Gapps and the Market) from Titanium backup, or will the backups be wiped out so we have to sideload?
[G Tablet General] JasonSCarter:
You can't just sideload those back on there. You need the whole Google Services Framework and all that jazz. I have been told you would just need to reapply the Enchancement pack once you have the update installed on other posts. I have only had my tablet for a month, and haven't experienced an OTA update from Viewsonic yet after running the enhancement pack, so I am going to have to go with the experience of the other people that have had theirs longer and have went through the process before.

So the word is the OTA update will wipe out the enhancement pack, but you can easily just install it again once you are updated. Been told you can even still get OTA updates while you are running the enhancement pack, but I saw one post earlier in this thread that seemed to say he never got the update for the last update until he went back to stock.
[G Tablet General] Skempo:
So how many people have actually installed 3991?

Have te result been good or have there been issues as noted earlier in this thread?

I am running 3588 with the enhancement and it is running great, so I am a bit leary of updating if there are issues.
[G Tablet General] Butch1326:
Besides the folks who are upgrading to the 3991 release directly, there are a group of us (including myself) who are testing 3991 as part of the TnT Lite custom rom configuration (TnT Lite 4.3.0 Lite - TEST).

Please recognize that 3991 has not been officially released from Viewsonic. It is being treated as an Unit Test module (or beta).

There were significant changes in this version of the rom, so unless you are willing to accept that there will be issues that you may have to deal with along the way, it may be best for you to wait until the official OTA release.
[G Tablet General] roebeet:
I just released TnT Lite 5.0.0, which is based off stock 3991 (including the bootloader and kernel). It's been problematic for some, due to the pre-requisite to run it.
[G Tablet General] pagantek:
Agreed. i've had the same heartbreak of an apparent brick, followed by elation as I did the nvflash successfully.
[G Tablet General] lsu205:
3991 andenhancement pack

Anybody tryinstalling 3991 on a gtablet running 3588 with enhancement pack?
[G Tablet General] roebeet:
This came up elsewhere - I would NOT recommend it. Our experience has been that stock 3588 is the best pre-req to upgrade to 3991. In particular, you HAVE to have the 3588 recovery and not clockworkmod. That's because only standard recovery will update the bootloader, and the new bootloader is required to run 3991. Without it, the device will hang.
[G Tablet General] lafm15:
So what ur saying is that if I have the3588 plus enhancements Athenian need to remove the enhancement and just leave the basic 3588???
[G Tablet General] JasonSCarter:
Hmm...3/15 now, and no sign of the OTA update from Viewsonic. I went back to stack in anticipation of the 3991 update. I wonder if Viewsonic is still working on it, and 3991 isn't the official one that will be released.

Maybe roebeet can do another site scan to see if there is anything newer out there than the 3991 zip file.

I would go ahead and try TNT Lite 5.0, but if something REAL is coming from Viewsonic, I may wait still.
[G Tablet General] lsu205:
Since 3991 may cause havoc unless it goes over 3588 wouldn"t it be a wise move for anybody running 3588 with enhancement pack to either revert to stock 3588 before 3991 goes OTA or migrate to TNT lite 5x? Otherwise I could envision the OTA ,if it ever comes, to wreak havoc?
[G Tablet General] JasonSCarter:
Yeah, I had the enhancement packed installed, and thats why I went back to stock once I heard about the 3991 update because there were to many unknowns. Been back on it for about a week now in hopes the update would be out via OTA by now. Haven't seen it yet though.

May be a delay in the push out if you truly have to wipe user data from the new recovery menu to get to 3991 (or that may only be with the TNT lite install). Don't know how Veiwsonic would communicate that to users if you truly had to do that with the regular OTA update.
[G Tablet General] lsu205:
Back to 3588 from enhancement pack

If you go back to 3588 from 3588 + enhancement pack, to either get 3991 or tnt lite 5.x, is the tab still rooted?
[G Tablet General] Butch1326:
If you stick with either stock version of the rom (3588 or 3991), you will need to root the gtab on your own after the update. If you install 3588 base, then install TnT Lite 5.0.0, your gtab will be rooted (rooting is included with the TnT Lite custom rom update).
[G Tablet General] lsu205:
When i went back to 3588 stock, titanium backup would not run, said not rooted. Rooted with z4root. Titanium still would not run, same resaon. Put enhancement pack back on, Titanium runs fine. What in the world?
[G Tablet General] Butch1326:
I don't know exactly if z4root installs busybox, or if it does, which components of busybox it may install. I've always used SuperOneClick in the past. My assumption is that if you would have selected the Problems? button in Titanium Backup, then selected the Get BusyBox button to install BusyBox, you may have been fine.
[G Tablet General] lsu205:
fwiw

Vs supporttold me today anyday now an update is coming. IMHO that could be the overdue flash from Jan, the new flash that many already run 10.2, or 3991 goes ready for prime time. I am leaning towards going3588 stock for friday as a precaution.
[G Tablet General] lsu205:
I never tried thatbut did reinstall but no luck.also when I downloaded superoneclick antivirus tagged it
[G Tablet General] roebeet:
I scan every few days, and nothing so far since 3991.

The comment on 1.2 is very interesting for a few reasons:

1- It is a 1.2, which I never noticed before. So it's a "major update", even in their eyes. Makes sense. The last few updates were "1.1", and the November releases were "1.0.1".

2- There have been two areas where we've grabbed updates, from them. I usually check both, but area one seems to be UAT (historically) wheras area two usually is their released ROM. 3991 was in area two.

I'm actually hoping that they continue in this direction because, to be very honest, I placed my bets on TnT Lite 5.0.0 and going back would be a sweet PITN. At least if their next update is a 1.2 that means the TnT Lite 5.x users are already over the hump.

3588 and 3991 won't be rooted, but TnT Lite 5.0.x will be rooted.

Sorry for the delay -- you want complete stock 3588 as your baseline, BEFORE going to 3991. This is absolutely critical, especially stock recovery. Anyone who's tried otherwise ends up with a semi-brick. It's possible that older stock versions might work but you probably don't want to risk it.
[G Tablet General] janovak1:
I have 3588 + enhancement pack; how do I easily return to 3588 stock?
[G Tablet General] JasonSCarter:
Just use the links provided in this thread, download the zip file, and do the standard flash with the update.zip file and the recovery folder like you did to get the enhancement pack on to start with. It will wipe the enhancement pack out. Thats what I did.

So if VS is gonna update do they do it usually on friday's I havent flashed anything yet but i am about to flash tntlite 5.0.1 but if a update is coming tommorow maybe i should wait and check that out first!
[G Tablet General] lsu205:
I think if you read Roebeets excellent instructions on that tntlite 5.0 forum, when you flashed to 5.0, your OTA updater is disabled. You'd have to go back to 3588 or an earlier stock version. His tnt 5.0 has all the improvements and likely more (like Market) that the VS update will produce.
[G Tablet General] janovak1:
I apologize for having to ask this; however, I cannot find it by searching the forums. How do I create the "command" file in the recovery folder?

Thank you!
[G Tablet General] Butch1326:
The easiest way to do this is to download the TnT Lite 5.0.0 custom rom from the Development section of this forum. The download file is in .rar format. When you extract the files from the RAR (using a tool like WINRAR), you will find inside a recovery folder and an update.zip file. Inside the recovery folder is a command file. You can use that as your starting point.

If you plan to use your microSD card to update files on the gtab, make sure you change the text in the command file from SDCARD to SDCARD2
[G Tablet General] butchconner:
lsu205,

The antivirus finds z4root because the "rooting" process is inherently a hack!

Not a virus or malware attack. But it is hacking and taking control of the

computer via an unauthorized means (with your permission, of course!)

I think I said that right.

Rev
[G Tablet General] butchconner:
janovak1 and butch1326,

The command file is the same for all these updates for the standard update.zip process. (If you do it on the external miniSD card you have to edit the command file to change it to SDCARD2).

So I found a stock recovery folder with command in it and I copied it from my pc over to the /sdcard directory with the name "stockcommand". Now, if I need a command file for the recovery directory I can just copy it over and rename it "command".

BTW, some of the readers may not know that when recovery runs, it deletes the command file so you can't accidentally "do it again." So if you need to flash it again,

you have to copy "stockcommand" over to recover folder as "command" again.

If you knew this already, I apologize......

Gtab Sleeps forever

I just installed 3991 on my g tab yesterday. All seems working well but still there is a problem. After turning of the screen if I don't turn it on in a while then tab would shutdown and I need to restart from beginning.

Is it a bug or battery saver script from vs that I don't know but want to solve this thing. Don't know if anybody else encountered this problem on stock 3991.
